Tall p waves (\u2267 2.5 mm) occurred in about a third of the patients in each group and were attributable to right atriomegaly. 8 patients, 4 from each group, had prolonged P-R intervals (\u2267 17 s) resulting from increased P-R segment (7 cases) and prolonged P-wave duration (4 cases). Right bundle branch block was, however, more prevalent in group I (44%) than in group II (5 %), and is thought to result mainly from a paucity of conduction fibres in the atrialized right ventricle in Ebstein\u2019s anomaly and partly, in group II especially, from septal fibrosis. In both groups R-wave deflections in V3R and VI were reduced, probably because of a clockwise cardiac rotation and paucity of right ventricular muscle mass.<\/jats:p>","DOI":"10.1159\/000173485","type":"journal-article","created":{"date-parts":[[2008,11,10]],"date-time":"2008-11-10T05:48:13Z","timestamp":1226296093000},"page":"61-69","source":"Crossref","is-referenced-by-count":6,"title":["Electrocardiographic Abnormalities in Ebstein\u2019s Anomaly"],"prefix":"10.1159","author":[{"given":"F.","family":"Jaiyesimi","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"127","published-online":{"date-parts":[[2008,11,7]]},"container-title":["Cardiology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/karger.com\/article-pdf\/doi\/10.1159\/000173485","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,29]],"date-time":"2026-04-29T16:26:14Z","timestamp":1777479974000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000173485"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2008,11,7]]},"references-count":0,"URL":"https:\/\/doi.org\/10.1159\/000173485","archive":["Portico"],"relation":{},"ISSN":["0008-6312","1421-9751"],"issn-type":[{"value":"0008-6312","type":"print"},{"value":"1421-9751","type":"electronic"}],"subject":[],"published":{"date-parts":[[2008,11,7]]}}}
